RVA

RVA is a range of valve actuators for the control of valves in the ZTV/ZTR, ZTVB/ZTRB range. It is available in two different models: with 0-10V control signal and 3-points control . They are easy to mount and have a clear position indication which shows the position of the actuator. It should be mounted so that the drive rod is within 90° from the vertical line and the motor housing is on top. The actuator is short-circuit proof and protected against polarity reversal when connected. 

After cutting the supply voltage, the spindle position can easily be manually adjusted without using any tools. The disengagement button is pressed down and the knob is turned until the desired position is reached. The position is indicated by a 0 to 100 scale on the knob.

The RVA range conforms to the EMC requirements in the European harmonised standards EN60730-1 and EN60730-2-14 and carries the CE mark.
